Abstract
An under-well testing continuous tube with a thermocouple tube and a capillary arranged inside can be applied to the technical field of oil production testing in an oil field. A thermocouple tube is prearranged in a continuous oil pipe, a pressure measuring capillary is arranged in the continuous oil pipe, a hole is arranged on the wall of the continuous oil pipe, and the position of the hole is on the other side opposite to the side where the thermocouple tube is located. A welding supplement block is embedded in the hole on the wall of the continuous oil pipe, and the welding supplement block is welded with the continuous oil pipe. A round hole is arranged on the welding supplement block, the lower end portion of the pressure measuring capillary penetrates through the round hole on the welding supplement block, and the lower end portion of the pressure measuring capillary is welded into the round hole of the welding supplement block. The beneficial effect is that under-well pressure measuring can be achieved, temperature measuring parameters can be transmitted to the ground, and strength and sealing property of the pressure measuring capillary and the thermocouple tube can be improved.
Description
Technical field
The utility model relates to production and test technology for oil field, oil field, and particularly a kind of oilfield well testing is managed continuously, is that a kind of built-in thermoelectric idol pipe and downhole testing capillaceous are managed continuously.
Background technology
At present, need monitor temperature, pressure in the thick oil horizontal well recovery process.Need temperature thermocouple and pressure measurement capillary tube is prefabricated in coiled tubing, then at coiled tubing outer wall welding capillary tube pressure transmission hole.To carry thermocouple and coiled tubing capillaceous is lowered into the down-hole, and carry out horizontal well down-hole thermometric, pressure measurement, it is dynamic to analyze oil reservoir production.At present, lower end capillaceous is directly passed the coiled tubing wall and is welded on the coiled tubing wall, and pressure transmission hole capillaceous can import down-hole pressure in the capillary tube, and through capillary tube down-hole pressure is delivered to ground.Because capillary wall is too thin, 0.89mm is only arranged, weld bad meeting and cause the pad sealing-off seepage between capillary tube and the coiled tubing, and influence the transmission of pressure, make the well pressure measuring failure.
The utility model content
The purpose of the utility model is: provide a kind of built-in thermoelectric idol pipe and downhole testing capillaceous to manage continuously, can realize that testing pressure down hole and temperature measuring parameter are delivered to ground.
The technical scheme that the utility model adopts is: built-in thermoelectric idol pipe and downhole testing capillaceous are managed continuously; Mainly form by coiled tubing, thermocouple well, pressure measurement capillary tube and welding patch; Prefabricated in coiled tubing have thermocouple well, and thermocouple well has the pressure measurement capillary tube in a side of coiled tubing inwall in coiled tubing; It is characterized in that: porose on the coiled tubing wall, the position in hole is at the opposite side relative with thermocouple well; Be embedded with the welding patch in the hole of coiled tubing tube wall; And welding patch and coiled tubing weld together; On the welding patch, circular hole is arranged, the circular hole on the welding patch is passed in pressure measurement bottom capillaceous, and pressure measurement bottom capillaceous is welded in the circular hole of welding patch.
Described welding patch is oval, and the circular hole on the described welding patch is at an end of welding patch.
Summary pressure measurement welding process capillaceous.Consult Fig. 1.Trail coiled tubing 1 on ground, open a slotted eye, pressure measurement capillary tube 3 is drawn outside the elliptical aperture in coiled tubing 1 at the pressure tap place of coiled tubing 1.Through elliptical aperture, the filling multilayer heat-barrier material 5 in order, and heat-barrier material 5 place mats are on thermocouple well 2 tops.Support member 6 is put into heat-barrier material 5 tops of coiled tubing 1.To weld patch 4 and be stabilized in the welding position, adopt argon arc welding welding welding patch 4, weld pressure measurement capillary tube 3 then with pressure measurement capillary tube 3.When welding, there is support member 6 to form certain space between heat-barrier material 5 and the welding patch 4, guarantee sufficient space heat elimination.In welding process, heat-barrier material 5 plays the effect that protection thermocouple well 2 does not receive high-temperature damage.
The beneficial effect of the utility model: the utility model built-in thermoelectric idol pipe and downhole testing capillaceous are managed continuously, can realize that testing pressure down hole and temperature measuring parameter are delivered to ground, improve thermocouple well and pressure measurement capillary tube intensity and sealing performance.
